Abstract

The invention discloses a cable force calculation method and calculation device for an inhaul cable, and the method comprises the steps: collecting the time domain data of a target inhaul cable according to a preset time interval, and converting the time domain data into frequency domain data through employing a fast Fourier transform method, so as to construct a spectrogram; identifying all wavecrest data in the spectrogram by using a second derivative method; screening out first wave crest data exceeding a preset wave crest threshold value from all the wave crest data; determining second wave crest data in the first wave crest data according to a preset frequency interval; and calculating the cable force of the target inhaul cable based on the second wave crest data. According to the method, interference data can be automatically filtered from frequency domain data, the wave crest of the inhaul cable is recognized, the tension of the inhaul cable is accurately calculated, and then construction control and health monitoring of an inhaul cable structure are facilitated.

Description

technical field [0001] The invention belongs to the technical field of cable force measurement, and more specifically relates to a cable force calculation method and a calculation device of a cable. Background technique [0002] Traditional cable force calculations generally adopt manual identification of frequency values, that is, through manual identification of each frequency value on the spectrum diagram, the cable force calculation is performed based on the identified frequency values. The above-mentioned calculation of cable forces often relies more on manual calculations, and there will be certain errors, resulting in incorrect final cable forces, which will affect the construction control or health monitoring of cable structures. [0003] Therefore, how to provide a cable force calculation method and calculation device for a cable has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the present ...
